A6000 & Wildlife fast action shots

I got my A6000 and 16-70 mm about two weeks ago and this is my first time with Sony products. I have been a Canon shooter for 15-20 years . I have to say that based on my first two weeks with the A6000 it is a wonderful camera and I like it a lot .However when I bought it my thought process was if the image quality was up to what I get with my 5D2 set up that I would sell my my 5D2 and my L lens and lighten my load a little. While image quality of the A6000 is very good I find that it is not up to job for my wildlife photography. So now I plan to keep my Canon gear and my long L lens for wildlife and use my A6000 for most everything else.I see a lot of folks on here talking about downsizing and selling their Canon and Nikon gear but I think that if you shoot fast action with long lens you might want to think twice about that.
